To all whom "it may concern:

Be yit known that I, HARRY F.- SMITH, a citizen of the United States,residing at Lexington, in the county of Richland and State v of Ohio,have invented certain new and use- -fful Improvements in Processes forFeeding Fuel into Gas-Producers, of which thefollowing is aspecification.`

My invention relates to improvements'iu processes for feeding fuel intogas producers' A especially where the fuel contains relativelyvlargeproportions of volatile hydrocarbons.

| l l l l Its objects are,among other things; a ,proe vide principallyfor the maintenance of a perfectly continuous feeding action 'of thefuel,

conse uentl of a uniform proportion of volatl e hy rocarbons in theresulting gas; i

magazine,A and suitably controlling such steam delivery as to precludethe distillation l of hydrocarbons and their liberation in said '25fuel-magazine or producer above a vcertain pointtherein allsubstantially as hereinafter more fully disclosed andspecific'allypointed out by the claims. V

In the accompanying drawing illustratinga machine 'or apparatus of-atype adapted to' carry out the objects of my invention or l l l l iprocesses-Figure' 1 is a sectional elevation thereof, and Fig. 2 is aplan view of the same. By way of aiding an unuerstandmg of my V3,5invention or process, reference is made to said drawing, wherein 1designates the usual prodneer-chumber. air and steam supply pipe 3discharging therevinto aboutin u line with said fire-grate; a

5 magazine 9.

of the pipe or funnel 7, or by means .of porte. (not shown) arranged inthe producer-lining so as to take the gas ofi' around the circumference.If a uniform percent of Ahydrocarbon-gases be lrequired it is usuallynecessary to provide apparatus for-mechanically feeding the fueleontinuouslyinsmall amounts to the active portion of the iire and inthisway rigidly limit the amount 0th drocarbons 65 which may beliberated at any ne time. l.If a fuel-magazine be employed containin arelatively large amount of such fuel, t is 'magazinesoon becomes heatedthrou h con-' tact with the hot gases passing from t e producer and fromthe general heating up of the` apparatus, thereby liberating acomparatively large amount of volatile matter which amount continues togrow steadily less as the distillation of the fuel proceeds and is notby anv means maintained uniform.

n my process the relatively large fuel magazine 9 is provided, as by allof the space in the producer-chamber, above e horizontal` line touchingVthe lower edge of the funnel or 30 pipe 7. Distillation of hydrocarbonsin this part of the apparatus is prevented by admit ting or deliveringfrom above a supply of steam into the fuel through the pipe 4. Theamount of steam delivered is controlled by suitably actuating the valveof said pipe, which is to be justsuffic-ient to prevent the liberationof the. hydrocarbons in the fuel- The action of this steam can evidentlynot affect the fuel bedfurtherdown g than the bottom edge of the pipe orfunnel 7, since at this point the steam is swept out It has a fire-grate2: an

40 vulvedsteam-supply pipe 4 delivering into thc upper end ol' saidchamber; a gus-delivery pipe or outlet .Brand a charging hopper In theupper part of the chamber 1, about centrally thereof, is u funnel orpipe 7, suit- 45 ably lixcd und lnaccdin position preferably as shown,and with which connects theoutlet 5, said funnel or pipil being closed:u its upper end by n suitable closure or cup 8. All

of the foregoing parts. it. will be undcrstoml.

50 are of well known general outline, und there- -,fore will .not befurther described herein in detail.

In applying or carrying out this process. it

is essential that the outlet for the gas shall be 55 at some distancefrom the top ol' the proof the producer along with the outgoing gas. Theaction of the steam, thus introduced, is

" therefore to prevent the heating of the coal 95 in'lthe magazine 9,accordingly intercepting such hea-ting action until the coal has passedbelow themagazlne El and, as the coal can pass from said magazine intothc active prodducer.v This may bc provided for by lhc use ucts ofcombustion below only in a regular manner and in pro )ortion to theconsumption of fuel, it is evident that, by this process, u. perfectlycontinuous feeding of the fuel is nmintained :uid consequently u uniformpro-A l portion of the volatile hydrocarlmns in thc resultinggas.

g Also from the foregoing. it will .be noted that the carrying out ofthis process is practiced and cil'ected with great simplicity, facilityand economy. '1-

l claimg 110 l. The herein described process fdr feeding l'm-l intogas'producers, which consists in lili ing the producer to a level sothat the upper surface of the vfuel is above the gas outlet andintroducing a. coolingr mediumat-'a point above the gasoutlet.

2. The herein described process forfeeding ,fuel into gas producers,which consists in lling the producer ro a level'so that the uppersurface of the fuel is above the gas outlet and introducing a coolingmedium at a point 'charging the fuel into the producer magazine toa'point above the mouth of the gas outlet .and then introducing steamabove the surface of the fuel7 thereby subjecting all of the fuel abovethe gas outlet to the action of the steam and protecting all fuel belowthe gas outlet from the action of the steam int-roduc'ed above the fuel.

4. T he herein described process for feeding fuel into gas producers,which consists in delivering steam ,in a regulated quantity to thatportion of the fuel located above the gas outlet whereby to e'eetuallycool the fuel as it' approaches the active zone in the lower part of theproducer and effec-tuali)v preventing the distillation-of hvdrofcarbonsand the @cking of the coal at any point above the gas outlet. y

In testimony whereof I affix my signature, in presence of two witnesses.
